Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019854, here are decompositions:

5 + 1019849 = 1019854
53 + 1019801 = 1019854
71 + 1019783 = 1019854
83 + 1019771 = 1019854
107 + 1019747 = 1019854
113 + 1019741 = 1019854
131 + 1019723 = 1019854
137 + 1019717 = 1019854

Showing the first eight; more decompositions exist.
